水溶性螯合肥对章丘大葱产量及养分含量的影响

Effects of Water-soluble Chelate Fertilizer on Yield and Nutrient Content of Chinese Onion of Zhangqiu

通过田间试验,研究了施用螯合肥和习惯施肥对章丘大葱产量及养分含量的影响。结果表明,施用螯合肥处理的章丘大葱,葱白直径和株高均高于习惯施肥处理,具有较好的商品性。螯合肥处理的植株全氮含量最低,而全磷和全钾含量居中;各施肥处理的植株氮磷钾含量随生育期的变化明显,而施用螯合肥与习惯施肥的变化趋势基本一致。

The field experiment was conducted to study the effects of applying chelate fertilizer and conventional fertilization on the yield and nutrients content of Chinese onion of Zhangqiu. The results showed that the stalk diameter and the height of chelate fertilizer treated plants were higher than those of conventional fertilization treated ones, and had better commercial characters. The total N content was the lowest and the total P and K contents were intermediate in chelate fertilizer treated plants. The contents of N, P and K in all of the fertilization treated plants varied markedly during the growing period, and the chelate fertilizer treatment and the conventional fertilization showed the same tendency.
